Expand Tree View when not cached

[epp_b]

This is a very minor costmetic suggestion:

When I click the little "plus" (how technical sounding ) by the directory icon in the remote directory tree, have it expand, even when it is not yet cached (basically it would perform the same action as clicking the directory icon itself).

These folders can't be expanded by clicking on the plus because they don't contain any items within them. This is Windows behavior.
